COMBINED oEsK ANo siAT.

SPEOIFICATIOZN forming part of Letters Patent No. 615,867, datedDecember 13, 189 Application filed June 30,1897. Serial No. 642,952;(Nomodlz) Rapids, in the county of Kent and State of Michigan, haveinvented certain new and useful Improvements in a Combined Desk andSeat, of which the following is a specification,

reference beinghad therein to the accompanying drawings.

My invention relates to that class of combined school desks and seats inwhich various adjustments of the desk or seat are secured in connectionwith front and rear adjustment, so that the desk or seat may be adaptedin all respects to the size of the user. 7

My said invention consists of the special constructions hereinafterexplained.

In the drawings, Figure l is a side elevation of the invention with theseat and desk in their highest position. Fig. 2 is a detail view of thestandard.- Fig. 3 shows a partial Fig. 4 is an inside view of one of theside standards. Fig. 5 is a detached View of the desk. Fig. 6 is apartial section on line a a of Fig. 1.' Fig. 7 is a partial section online b b of Fig. 1. Fig. 8 is a partial section on line cl d of Fig. 1.Fig. 9 is a view of one of the supports. Figs. 10 and 11 show minordetails.

The standards consist of side frames E,with flaring lower portionsterminating in feet gradually tapering to the upper end. The seat 2 andback 3 are secured to supports F, arranged one at each side, and thesesupports are connected by a foot-rest I, as shown in Fig. 1, and thesesupports,with the foot-rest, seat, and back, constitute a frame. Thisframe is adj ustably supported upon the standards E, fittingslightlywithin the same and bearing on the inner faces thereof. Theconnection is made by studs R on the standards entering inclinedelongated channels 11. in the adjacent faces of the parts F of theframe, and to prevent displacement in the adjustment of the frameprojections a on the parts F pass in front of overhanging lugs 19, asshown in Fig. 7. The connection at the upper end between the supports Fand the standards is made by inclined slots N in the supports F, throughwhich bolts 'l-I pass, extending through the standards, each beingthreaded upon its outer end to receive a nut. By reason of the in'-clined slots N bearing on the bolts and the inclined channels a it willbe observed that as the supports F are moved up and down they will alsohave a movement backward or forward in relation to the standard, andthus automatically change the relation between the seat and the deskimmediately in front of said seat, bringing the seat and desk nearertogether or increasing the distance between them, according as thesupports F are moved downwardly or upwardly.

The bolts securing the supports F and stand= '6 5 ards E together havetheir heads resting on projections 0, extending from the inner faces ofthe standards just beneath the bolt-opening, and these projections notonly serve to support the bolts when the nuts are loosened, butalso-serve to direct the supports F in their vertical movement. Thesupports F are not only connected by the back and the seat, but also bythe foot-rest. This foot-rest is secured to the supports by a nail orscrew at each end, and as the foot-rest keeps the supports separated andthe projections or studs R enter the depression and groove in thesupports from the outer faces of the supports it will be seen that eventhough the fastening- 8o bolts be withdrawn the seat and back framecannot be removed without displacing the foot-rest and the back. Thefoot-rest I is secured by fastenings passing through the supports F intothe ends of the foot-rest, and as the points where the fastenings passthrough the supports are concealed by the front edges of the standards Iprovide an enlarged opening d through the front edges,adapted toregiste'r with the screws in the supports, andthus 9o permit'thewithdrawal of the same, when desired, through these openings d.

The desk is composed of the side sections G, connected by the top P andthe shelf Q,

and the frame thus constituted is connected I to the standards fittingthe recessed edges of the said standards. A stud S engages an inclinedslot M in the standard and a bolt passes through the desk-frame abovethe stud S, which support-s the head of the bolt and through theinclined slot. A second inclined slot L is made in the recessed flangeof the standard, this being partially covered by a raised web d, and ahook e in the lower edge of the desk-frame engages this slot and guidesthe desk-frame at this point.

The slots M and L are inclined in the opposite direction to the slot Nand depression u, as it is essential that the desk-section should changeits relation in a direction opposite to that of the seat and back frame.

In order to give a finish to the standard when the desk-section islowered, I provide a cross-piece Y, which is exposed when the desk islowered and is covered when the desk is raised.

What I claim is- 1. The standards E, having studs R, the bolts H passingthrough holes in said standards, in combination with connected supportsF carrying the seat and back and having inclined channels it for thestuds, and slots for the connecting-bolts, the parts being constructedand connected, substantially as described.

2. The standards E having studs R the bolts H passing through holes insaid standard in combination with connected supports F carrying the seatand back and having inclined channels a for the studs, and slots for theconnecting-bolts and supporting and directing projections, the partsbeing construct ed and connected substantially as described.

3. The desk composed of the standards the side sectionsG, connected asdescribed, and fitting the standards, having recessed edges, and havingalso a stud S engaging an inclined slot M in the standard, a hook c inthe lower edge of the desk-frame engaging an inclined slot L in therecessed flange of the standard, a raised web d and means for holdin gthe parts together all substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
